For Brownout we have terms and definitions in 4 topics. The topics are Energy, Technology, UPS and Uk Power.

Brownout (Energy)

A controlled power reduction in which the utility decreases the voltage on the power lines, so customers receive weaker electric current. Brownouts can be used if total power demand exceeds the maximum available supply. The typical household does not notice the difference.

Brownout (Technology)

A condition in which the electricity level is appreciably reduced for a sustained period of time. In contrast to a blackout, or total loss of power, a brownout continues the flow of electricity to all devices connected to electrical outlets, although at lower levels than the normally supplied levels (120 volts in the United States). A brownout can be extremely damaging to sensitive electronic devices, such as computers, because the reduced and often fluctuating voltage levels can cause components to operate for extended periods of time outside the range they were designed to work in. On a computer, a brownout is characterized by a smaller, dimmer, and somewhat fluctuating display area on the monitor and potentially erratic behavior by the system unit. The only reliable means of preventing damage caused by a brownout condition is to use a battery-backed uninterruptible power supply (UPS). See also UPS. Compare blackout.

Brownout (UPS)

A reduction in the voltage of the AC utility without complete loss of power.

Brownout (Uk Power)

The partial reduction of electrical voltages caused by customer demand being higher than anticipated or by the failure of the generation, transmission, or distribution system
